Action and Reaction Pairs (Newton's Third Law)

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What happens when a rocket engine burns?

Back

Hot gas flows downward, producing an upward thrusting force.

Front

What is an example of an action-reaction pair in sports?

Back

When a player kicks a soccer ball (action), the ball pushes back on the player's foot (reaction).

Front

How does a swimmer move through water?

Back

By pushing water backward (action), the swimmer is propelled forward (reaction).

Front

What is the role of friction in action-reaction pairs?

Back

Friction can affect the motion by opposing the action force.

Front

What happens to a balloon when air is released from it?

Back

The air pushes out in one direction (action), and the balloon moves in the opposite direction (reaction).
